In a summer long overshadowed by the uncertainty surrounding the futures of Cesc Fabregas and Samir Nasri the signing of Lille forward Gervinho has, at least temporarily, lifted the gloom over the Emirates.
The capture of the 24-year old Cote d'Ivore international was announced last week but the paperwork is now complete for Arsene Wenger's first major signing of the summer.
"It's a great feeling to be an Arsenal player," the striker said.
"I'm very happy. I've always dreamed to play for this club. I've achieved this dream now and I am so happy. It's one of the most beautiful days of my life.
"I'm very happy to have the chance to work with Arsene Wenger. I came here because I believe that he can improve my game and help me reach another level, but the most important thing for me is that I bring a lot to the team for whom I'm playing."
The Ivorian scored 18 goals in 49 games last season, as Lille completed the Ligue 1 and French Cup double.
"Gervinho is a player that can play in a number of position up front," Wenger said. "He can play on the right, on the left and through the middle. He has qualities that I find very important, like his movement off the ball. He has the qualities we like technically. He is good one against one, he is strong and was the best provider in the French league with assists and he scored 15 goals. I think he is a very good addition to the squad."
Arsenal continue to be linked with Gervinho's Lille teammate Eden Hazard, as speculation surrounding Samir Nasri's Gunners' future continues.
The 20-year-old Belgium international has attracted interest from a number of top European sides after helping Lille to their first French league title in 46 years.
Barcelona, Real Madrid and Paris Saint-Germain have all also been linked with a move, despite the club's general manager Frederic Paquet issuing a stark "hands off" warning last month.
"Eden is not for sale. He will not be leaving this summer, whether to Paris or anywhere else," Paquet said.
Meanwhile, Arsenal are "keeping tabs" on Napoli midfielder Marek Hamsik and Valencia's Ever Banega, according to reports over the weekend.
Hamsik, one of the standout performers in Serie A last season, has also been linked a move to Man Utd or AC Milan.
But Napoli coach Walter Mazzarri is confident the Slovakian international will be at the club next season.
"Marek is happy to work with me and he is very motivated. He is happy to remain here.
"I have spoken to him and from what I know, in the end he will not leave."
Hamsik joined Napoli from Brescia in 2007 and is under contract with the club until 2015, ESPN Soccer reports.
Van Persie threat
Finally, reports this morning suggest that Real Madrid are lining up a £30m bid for striker Robin van Persie.
The Dutch international has been openly critical of Arsenal's activity in the sumemr transfer market and the Metro claims that Jose Mourinho is ready to tempt van Persie to the Bernabeu.
Mourinho sees van Persie as a more potent attacking threat than either Gonzalo Higuain or Karim Benzema and is prepared to splash out on the 27-year-old.
